Mountain Climber
by Jace
Running in a plank — a quick way to lift the pulse with no equipment and almost no noise.


How to do it
- Start in a high plank, hands under the shoulders, body in one straight line.
- Drive one knee toward the chest, then switch legs in a steady running rhythm.
- Keep the hips level with the shoulders and the hands pressing the floor away.
- Start slowly and build the pace while the plank stays solid.
